A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.
The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,
r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)
Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2
The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°
Hence, the polar coordinate is <em>(4√2, 315°)</em>
The complement of at least one television being defective of 15 shipped televisions is that none of the television is defective.
Answer:
The price before increase = 1255.5
Step-by-step explanation:
7% of 1350 = 
= 94.5
The price before increase = 1350 - 94.5
The price before increase = 1255.5
The answer to the problem is 44 in^2.
